You can put this solution on YOUR website!
Currently you have 2/33 gallons of oil (2 gallons of which 1/33 is oil). You wish to achieve the ratio 40:1 so you need 40 times more gasonline = 40*2/33 = 80/33. Currently you have 64/33 gallons of gasoline in the mixture so you need to add 80/33 - 64/33 = 16/33. \n" ); document.write( "
